摘要：

Ce(3+)-doped strontium alumino-silicates (Sr(1-nu)M(nu))(1+y)Al(2-x)B(x)SiyO(4+3y) (M Ca,Mg,Ba) were prepared using solid-state reactions at 1200 degrees C for 2 h in a weakly reductive atmosphere of 5% H(2)-95% N(2) The X-ray diffraction measurements revealed that the products have a good crystallization, and the resultant phosphors show broad emissions centered at 400 nm, with a long-persistence of several minutes (k = 0.02-0.10 s(-1)). These luminescent properties are considered good enough for novel applications in photo catalysis, which will be the objective of further developments (C) 2010 Elsevier B V All rights reserved
